WEBDISPATCHER

[former_member385237]

I have configure webdispatcher on separate server which is on live ip for portals.

When i access through local link in premises(http://abc.gxt.pk:50000) and test the connection with back-end system , logon ticket method works perfectly.

When i access through dispatcher from link(http://webdisp.gxt.pk:8101) and test the connection with back-end system, it shows me logon page and ticket method does not work.

Access links are different but server is same.

Please suggest if any one is aware of this problem.

Hi Uneeb,

Just to be sure, are you using Webdispatcher hostname for ABAP backend system in "ITS" and "Web As" sections of the system?

If not, please change it and try.

Thanks,

Hi,

It seems that Webdispatacher is working correctly.

what did you mean " it shows me logon page and ticket method does not work." exacly ?

maybe it's better to upload the screenshot which show the error.

Thanks and best regards,

Shi

[former_member385237]

This one is fine and from local link

This one is not working correctly if going on same server from dispatcher.

Hello Uneeb,

Please check this document

scn.sap.com/docs/DOC-16078

Thanks,

Hardeep

[former_member227283]

Hello Uneeb,

If I am not wrong on the internal page your domain is *.oul.pk as well as your back end system domain is *.oul.pk where everything is working fine.

Now in your web dispatcher scenario you webdipatcher URL domain is *.oul.edu.pk and back end system domain is *.oul.pk , if this is correct then this is a problem where due to cross domain sap sso ticket is not getting authenticated and you are getting logon page.

To solve this problem you should configure webdipatcher with second URL bypass i.e. of backend so you can call the backend page with same domain as webdipatcher and same details should be maintained portal system object for backend.

Or you have to configure sap cross domain scenario to authenticate the tickets.

Regards,

Anil Bhandary

[former_member385237]

Could you tell me more about cross domain scenario to authenticate tickets ?

[former_member227283]

Cross domain is bit complicated when you perform integration with multiple sap components.

Pls refer the below link

I would suggest to modify backend URL by using  webdipatcher which will help to bring common domain and which will resolve your problem.

Regards,

Anil Bhandary

[isaias_freitas]

Hello Uneeb,

At your Web Dispatcher profile, I see:

wdisp/system_1 = SID=EPD, EXTSRV=http://uolepd:50000, SRCSRV=*:81$$, SRCURL=/irj/;/
wdisp/system_2 = SID=RCD, EXTSRV=http://uolrcd:50000, SRCSRV=*:8101, SRCURL=/irj/;/
wdisp/system_3 = SID=PIP, EXTSRV=http://uolpip:50000, SRCSRV=*:8102, SRCURL=/irj/;/

Are these SAP NetWeaver Java systems?

If yes, you should not use "EXTSRV", but configure them in the same as you did at "wdisp/system_4 = SID=ERD, ...".

In addition, you would have to adjust the System Object at the Portal, pointing the "ITS" and "WebAS" properties to the Web Dispatcher instead of directly to the backend.

The Configuring the Web Dispatcher for Multiple Systems - Clarifications and Examples - Application Serv... WIKI page might help you with this setup.

Regards,

Isaías
